[amibroker] Re: Nested Switch() statements

Personally, I found TJ's reference to the Wikipedia explanation 
helpfull: http://en.wikipedia.org/wiki/Switch_statement.

One of the points it makes is that it is "easier to read and maintain 
than an equivalent series of if-else statements, because it is more 
concise." 

However, it also warns that ". . .when implemented with fall-through, 
switch statements are a frequent source of bugs among programmers new 
to the switch statement."
